It has a large 7-inch display

The new Kindle Oasis has a 7-inch screen, the largest on any Kindle and 1-inch larger than on the first Kindle Oasis. It offers 300 pixels per inch, which means text is always sharp and easy to read.

It's water-resistant

Text is still really crisp

It's the first water-resistant Kindle. Amazon says it can withstand 3 feet of water for up to 30 minutes without damage. Amazon said it made it water-resistant because customers like to use Kindles while in the bathtub.

It has an aluminum body

The back has a really premium aluminum finish

The back of the new Kindle Oasis is aluminum, which gives it a premium look and feel. Amazon previously used plastic, and this definitely feels like a nice upgrade. It's super comfortable to hold and has a built-in battery on one side that feels nicely balanced.

It can read books to you

It can read books to you through Audible

The Kindle Oasis sports built-in Audible.com support, which means it can read books to you so long as you have an Audible subscription (or own an audio copy of the book through Audible.) You can pair the Oasis with a Bluetooth speaker, tap a button, and it starts reading right from where you stopped.

You can customize the text to your liking

There are all sorts of text customization options to fit your reading style

Amazon added all sorts of customization options in the settings so that you can make the book look exactly how you want it to. You'll be able to adjust the font size, add different levels of bold to text and even change alignments.

It offers 6 weeks of battery life

CNBC | Todd Haselton

It's a good deal larger than the original Oasis but still easy to hold

Amazon said the Kindle Oasis will keep running for up to six weeks. And, in case you need to add some juice before hopping on a flight, it'll fully charge in just two hours.
